BBC Nature - Corals inflate to escape being buried alive in sand 8 February 2012Last updated at 03:38 By Victoria Gill Science reporter, BBC Nature Footage captured over 20 hours shows the coral inflating and deflating to throw off sand Coral might appear solid and inanimate, but surprising new footage of a mushroom coral inflating itself to escape a sandy burial has brought the organism to life. A scientist from the University of Queensland used timelapse photography to capture the footage. It was already known that the species could release itself from the sandy seabed, but it was not clear how. Since corals move so slowly, time-lapse imagery was used to find out. Dr Pim Bongaerts captured the footage and published his findings in the journal Coral Reef. As sandy sediments shift on the seabed, corals need to breathe and prevent themselves from being smothered. "Sedimentation presents a major threat for corals, as they can become covered in a layer of sand from which they are unable to escape," explained Dr Bongaerts. Inflate and deflate

Non-Trashy Recycled and Trash Art Artists are usually ahead of the curve when it comes to being green. The artists featured here exclusively use recycled and/or trash to make pieces of contemporary art. These artists practice the art of “upcycling”, or literally turning everyday trash into creative treasures. While Andy Warhol may have made the idea popular with his famous Campbell’s soup can exhibit, today’s trash artists bring more of an eco street cred to their art. Some create compositions from recycled plastic bag or themed works for art galleries, while others create entire theme parks with trash, and even furniture from recycled materials. There seems to be no end to what kind of art you can create with the most cost-effective medium available; trash.

Vik Muniz The author arranges all of the pieces carefully, photographs the collages, and then destroys them so that they only exist as photographs. Bernard Pras David Mach
